at least one polyethylene glycol having a number average molecular weight of from 1,000 to 2,000:
wherein R 11 and R 12 each independently represents a hydrogen atom or an alkyl group; R 13 and R 14 each independently represents a hydrogen atom, an alkyl group or an aryl group; R 15 represents an alkyl group having at least one asymmetric carbon atom, or a group represented by the following formula (I-a); R 16 represents an alkyl group having at least one asymmetric carbon atom, or a group represented by the following formula (I-b); and M 1 represents a hydrogen atom, an alkali metal atom, an alkaline earth metal atom, an ammonium croup or a pyridinium group; R 13 and R 15 and R 14 and R 16 may be bonded to each other to form a ring;
—CH 2 O(CH 2 CH 2 O) n 11 H (I-a)
wherein n 11 represents an integer of from 1 to 3;
—(CH 2 CH 2 O) n 12 H (I-b)
wherein n 12 represents an integer of from 2 to 4.
2. The liquid processing composition for a color development of a silver halide color photographic material as claimed in claim 1 , wherein in formula (I), at least one of R 15 and R 16 includes a hydroxyl group.
3. The liquid processing composition or a color development of a silver halide color photographic material as claimed in claim 1 , wherein in formula (I), R 11 , R 12 , R 13 and R 14 each independently represents a hydrogen atom or a methyl group, R 15 is a group represented by formula 2), 5) or 11) below, or a group represented by formula (I-a) wherein n 11 is 1, R 16 is a group represented by formula 17), 20) or 26) below, or a group represented by formula (I-b) wherein n 12 is 2, M 1 is Na or K:
4. The liquid processing composition for a color development of a silver halide color photographic material as claimed in claim 1 , wherein the at least one glycol is selected from the group consisting of diethylene glycol and triethylene glycol.
5. The liquid processing composition for a color development of a silver halide color photographic material as claimed in claim 1 , which.comprises the compound represented by the formula (I) in an amount of from 1 to 50 g/liter of the amount of the composition.
6. The liquid processing composition for a color development of a silver halide color photographic material as claimed in claim 1 , which comprises the glycol in an amount of from 5 to 100 g/liter of the amount of the composition.
